Question:

How else can I take the drill bit off?

My drill iron chuck is missing. How else can I take the drill bit off?

Answer:

The drill bit comprises a cutter rod, a cutter rod, a tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E) on orientation short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end.
New drilling machines that use electricity as power. Is the power tools in the conventional products, but also the largest demand for power tools products. 35% of China's power tools are produced and sold each year. The main specifications of electric drills are 4, 6, 8, 13, 16, 19, 23, 32, 38, 49mm, etc. the figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm2 (). For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.
In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
